Well.Thank-you Delta².Yes the "k" has to be plus.You know customer's request is the G-force of the machine from 1G to 6G.As one of forum friends said that it is 1G during shipping if the road is smooth without rush ,hole and slop.So when the truck went through a hole or a slop it seems that the...

Yes,I am sure it is "mm".My purpose is to calculate the Max and Min G-force of the machine during shipping.The shock absorber is made from rubber and metal.When the machine put onto the 4 shock absorbers it will move down 2.365mm.I did not convert to the meters just because it can be ignore when...

Thanks for everybody's help. I learned more from the forum.I want to know vertical G-force calculation."acceleration/9.8"is the G-force or it's wrong. Thanks again.

Yes,you are correct.I considered the tilted and fastend the machine onto the truck.The machine can not horizontal moving and just have a short vertical moving.My question is that I do not know the vertical G-force during shipping. Thank-you

Yes,you are right.I know how large the Maximum weight of the shock absorber can support about 1700kg and I know the shock absorber moving down as limit about -5mm. Thank-you

So,that's the G-forces calculation,right?I just need to make sure the units of acceleration.The "a" I mentioned to just calculate as a=(kx-mg)/m."k" and "x" provided by supply."m" is the weight of the machine and "g=9.8N/kg".k=F/x=1700x9.8/-5(mm)=-3332.So,a=((-3332)*(2.365-5)-1125*9.8)/1125=2.So...

Thanks for everyone's help. Sorry,m/s^2 the same as N/kg caused when you use different unit. "a" is the acceleration(vertical and horizontal).Yes,the 4.5 Tons is based on 4 shock absorber then each shock absorber gets about 4.5/4=1.125 Tons of weight. When the truck went through a sloping or...

You mean mg=GmM/r^2,g=GM/r^2.Usually,g=9.8kg/N=9.8m/s^2.Right? The situation is that when a 4.5Tons machine put onto the shock absorbers(x4).How to calculate the machine's vertical G-force during shipping.I calculated the acceleration of the vertical a and use a/9.8.It means "a/9.8" is the...

Hi, I eager want to know about how to calculate the vertical G-force.I have some ideas but I do not if it is right or not.I just calculate the acceleration first,then use a/9.8 kg/N or m/s^2. Is this formula right or not?Is someone can tell me? Thanks in advance.
